Description

Evaluation of the reaction rate from the carbon, hydrogen and oxygen in coal to those in gasified gas in our fluidized bed coal gasification experiments with a devolatilization reaction of coal and an oxidation reaction by oxygen was made. The experimental apparatus had a coal feed capacity of about 6 kg/h at pressures of 1.2 and 2 MPa and at temperatures of 1, 100 K to 1, 400 K.<BR>By arranging the experimental data for CO and H2 production rate and CH4 production rate, the simplified coal gasification reaction rate from carbon, hydrogen and oxygen in coal to those in gasified gas was acquired. Both equations of char gasification rate and methane conversion compose the simplified coal gasification reaction rate.<BR>The value and temperature dependency of the char gasification rate per unit carbon with devolatilization and oxidation reactions in the fluidized bed were generally the same as those of the char gasification rate without those reactions in previous studies.<BR>Using the acquired simplified coal gasification reaction rate for 6 coals, the calculation method of the mass balance in coal fluidized bed gasifier was presented.
